La presa de Hidroituango tiene una altura de 225 m., alberga 20 millones de m^3 de volumen y una cresta de 550 metros de longitu

bija089 [108]

Answer:

El ancho de la superficie = 444,44 my el largo = 200 m

La superficie de la superficie de la presa = 88888,89 m²

Step-by-step explanation:

Los parámetros dados son;

La altura del agua en la presa = 225 m

El volumen de agua en la presa, d = 20 millones de m³

La longitud de la base = 200 m

Sea el ancho de la presa = x

El volumen viene dado por la relación;

200 × 225 × x = 20 millones de m³

x = 20.000.000 / (200 × 225) = 444,44 m

Por tanto, las dimensiones de la superficie son ancho = 444,44 my largo = 200 m

El área de superficie de la superficie de la presa = 444.44 × 200 = 88888.89 m².

babunello [35]

Answer:

y4 - 8y3 + 8y2 + 2y + 8

—————————————

2y2

Step-by-step explanation:

Step 1 :

Simplify ——

Equation at the end of step 1 :

y y 4

(((((y2)+————)-((2•—)•y))+——)-4y)+4

(y2) 4 y2

Step 2 :

Simplify —

Equation at the end of step 2 :

y y 4

(((((y2)+————)-((2•—)•y))+——)-4y)+4

(y2) 4 y2

Step 3 :

Simplify ——

Dividing exponential expressions :

3.1 y1 divided by y2 = y(1 - 2) = y(-1) = 1/y1 = 1/y

Equation at the end of step 3 :

1 y2 4

(((((y2)+—)-——)+——)-4y)+4

y 2 y2

What is the area of a regular pentagon with a radius of 6 cm?

nikitadnepr [17]

Answer:

85.6 cm^2

Step-by-step explanation:

The area of the central triangle bounded by each of the sides can be computed as ...

A = (1/2)r²sin(α) . . . . where α is the central angle, 360°/5 = 72°

There are 5 such triangles, so the area of the pentagon is ...

A = (5/2)(6 cm)²sin(72°) ≈ 85.595 cm²

The area of the regular pentagon of radius 6 cm is about 85.6 cm².
